Cuando una luz de 1,6x1015 Hz de frecuencia incide en una superficie metálica, los electrones empiezan a abandonar la superficie (frecuencia umbral). ¿Cuál es la velocidad máxima de los fotoelectrones emitidos desde esta superficie cuando la luz con frecuencia de 2,45x1015 Hz cae sobre el material?
